well now maybe possibly the board issue is with a bpc that ironically is controlling power to mainline that big boy was on it appears that this bpc no longer responds to any cab-2 commands will not accept id number if plug removed for programming and after the plastic clip reinstalled cannot get green light to respond to any commands nor can i change from t1 to t2 as i use t2 to run in conventional mode and yes i do run conventional at times like this when ive just had enough of the latest greatest electronics gremlins running amuck so a loooooooooong time ago when lionel changed the way bpcs controlled track sections i had found some of the older ones in stock and in my stash I found one so will replace the bad one and once tvs arrive will install that as well as for somehow stopping fluid from soaking rcmc board not sure how to stop that as boards need some air for heat to dispense otherwise a raincoat would work well pun intended

One of the best ways to help protect your engine’s electronics is as had been said installing transient voltage Supressors. The can easily be installed on all the outputs of your transformers and if you use other devices like ASC’s or other controllers Ike TPC’s install them on both the inputs and outputs.
You can purchase them from Newarks and other electronic suppliers they cost about $1.00 each.
I would recommend the following TVS: 1.5KE33CA
It will protect you from any voltage spike above 33 volts and safely direct it to ground. No need to install them in engines unless you run your engines somewhere other than your layout. the website you referred to has a choice of ten with that number so which one is correct one or does it not matter?

No disrespect from the poster but Newark sucks. Buy from Digikey or Mouser.

I would definitely check to see where the short is on the layout. Other wise you are going to be replacing another. What kind of track are you using? no short that i know of this happened at startup engine sitting idle no wheels or errant strand of wire on track only thing is this one the smoke fluid i added to blow down for whatever reason went all over the rcmc board so am thinking a fluid caused short? they really put that board in a bad spot I've been using combo gargraves and ross track for 20 some years now I use the same combination of track, can you put a diverter in the boiler so when you overfill the fluid will not run over the board?

Also, check the output of whatever your final device to the track is (BPC?) when set on maximum and make sure it is 19 volts or less. It's conceivable you are outputting much more to the track and this is blowing your boards. Lionel electronics are rated for a maximum of 19 volts I believe, although I'd guess 18 volts is safer. Make sure you have both current limitation (circuit breaker like one of the PSAX series) and voltage limitation (transient voltage suppressor across the power outputs at the transformer, or internal to the locomotive) on your power to the track to protect the locos.

I try to keep track between 18-19 volts I use a volt meter to set it at all track locations BPC is block power controller you can turn power on/off to each isolated track section
as for a diverter well the boiler cover covers the switches that control the various features that also serves as a holder for fill tube to blow down smoke unit that has no room for anything but I wonder if I could cut a piece of an electronics static bag and make a cover so if nothing else sheds fluid to track the plastic molded filler tube should have been a solid piece instead of a split into 2 halves as screws do not seal them well so fluid goes where it shouldn't I often wondered why they didn't create a small cover or ? over the fill hole directly to blow down smoke unit like they did for the atsf steam engine had a hole in boiler where you filled the smoke unit
I did switch out that bpc that wasn't responding to cab-2 all works as intended now but alas the queen is still under the weather and changing that rcmc is not a picnic for fat fingers thanks to all that have replied much appreciated

I'm assuming as long as I order the tvs that appears like a transistor that any one of those will work as apparently they have a bunch of manufacturers that make them is there a specific one I should order as most say 28.2vwm 45.7vc do not have a clue as to what that means i told you I'm not an electronics person

With TMCC/Legacy don't go over 18 volts, PS2/3 have no problem with with 20 volts, Lionel not so much.

i think i found it shows 2 of them in photo with the stripe on one showing at top other at bottom assuming those are correct ones

As far as where to buy them it doesn’t matter to me I just could not think of the other suppliers I’ve purchased from Digikey. They seem to have good prices and reasonable shipping.

Well I've never heard that before and something I'm not going to try. I have heard of Legacy boards being damaged over 20 volts while running.
